The IPR-RRD access doors of the METU System for round ducts
are the most versatile access opening closures. They fit nearly
all diameters of spiral ducts — from 68 to 1800 mm — and are made
from various materials such as galvanized steel sheet and stainless steel.
The access door sizes meet the requirements of EN 12097 and can be tailor-made
according to individual specifications if access openings larger than those
defined in industrial standards are required.
The METU System covers a range of different gasket types and materials;
as a result, the IPR-RRD access doors made from stainless steel sheet offer
resistance up to 300˚C. Standard gaskets are made from PE.
